MEANS FOR RAISING SUNKEN LOGS.

SPECIFICATION forming part of Letters Patent No. 720,137, dated February10, 1903.

Application filed June 23, 1902. Serial No. 112,879. (No model.)

To all whom it may concern:

Be it known that I, BERT H. HARRIS, a citizen of the United States,residing at Reed City, in the county of Osceola and State of Michigan,have invented certain new and useful Improvements in Means for RaisingSunken Logs; and I do hereby declare the following to be afull, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in means for raising sunken logs;and its object is to provide the same with certain new and usefulfeatures hereinafter more fully described, and particularly pointed outin the claims, reference being had to the accompanying drawings, inwhich Figure 1 is an elevation of a device embodying my invention; andFig. 2, an enlarged detail of the lower portion of the same, shownpartially in vertical section.

Like letters refer to likeparts in both figures.

A represents a sunken log with my device attached thereto; 13, anysuitable hoisting means, the device shown being a hoistingcrane; O, asuitable support for the same, that shown being a floating scow.

D is a hoisting-line attached to the crane and having attached to itslower end a dog E,

adapted to be driven into the log to be raised,

for which purpose it is provided with a suitable flange E, engaged by asuitable socket F, within which is a pointed and shouldered extension Eon the dog. The shoulder'of this extension is engaged by a suitable hookG to hold the dog detachably connected to the socket F. This hook isheld in engagement with the shoulder on the dog by a spring G. This hookis released by means of a cord H, extending upward to some suitableplace near the crane B. The socket F is provided with a collar F,securely welded or otherwise attached thereto, and outside this socketand longitudinally movable thereon is a tube I to operate as a hammer todrive the dog E into To permit the longitudinal movement of this tube Ion the socket F and to a ring I is secured in the lower end of the tubeI and another ring F is attached to the upper end of the socket andadapted to traverse the interior of the tube and to engage the ring I toprevent detachment of the socket from the tube.

Attached to the upper end of the tube I by a suitable coupling is ahandle J tooperate the device. This handle is preferably of iron pipeand extensible by attaching additional sections by means of suitablecouplings K;

From the foregoing description. the operation of my device will bereadily understood. The dog E is first driven into the log by repeatedblows of the hammer I upon the flange F. The dog is then released bypulling the cord H and the remainder of the device hoisted out of theway. The line D now being se curely attached to the log, the same can behoisted to the surface by means of the crane B and further disposed ofin any convenient manner.

Instead of a crane B and scow C aboat can be used for manipulating thedevice for driving the dog into the log, and the line D may be led tothe shore or to any other convenient point and the log moved thereby, asmost convenient.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is I 1. The combination of a dog, a socketdetachably connected thereto, a reciprocating hammer connected to thesocket, a handle to operate the hammer, and a line attached to the dog.

2. p The combination of a doghaving a flange and a shouldered extension,a line attached to the dog, a socket to receive the extension andengaging flange, a hook on the socket to engage the shoulder, a cord torelease the hook, a reciprocating hammer attached to the socket, and ahandle to operate the hammer.

3. The combination of a dog, a socket detachably connected to the dog, acollar fixed on the socket, a tubular hammer surrounding the socket andlongitudinally movable thereon, and a handle connected to the hammer toreciprocate the same.

4. The combination of a dog,a line attached to the dog, a reciprocatinghammer detach- IOG ably connected to the dog, and an extensible handleconnected to the hammer to operate the same.

5. The combination of a dog, a tubular socket detachably connected tothe dog, a collar fixed on the socket, a tubular hammer surroundingthesocket and engaging the collar, a ring attached to the interior ofthe hammer and traversing the socket, and a ring attached to the socketand traversing the interior of the hammer, and a handle to operate thesame.

6. The combination of a dog havingaflange and a pointed and shoulderedextension, a tubular socket engaging the flange and surrounding theextension, a pivoted hook, and a collar fixed on the socket, a ringwithin the hammer and traversing the socket, a ring on the sockettraversing the interior of the hammer, a sectional handle to operate thehammer and couplings connecting the sections of the handle.

7. The combination of a suitable scow or float, a hoisting-crane mountedthereon,aline attached to the crane, a dog attached to the line, areciprocating hammer detachably connected to the dog, a handle tooperate the hammer, and a cord to detach the hammer from the dog.

8. The combination of a dog,aline attached to the dog, a hammerdetachably connected to the dog, a handle to operate the hammer, andmeans for detaching the hammer and dog.

In testimony whereof I aflix my signature in presence of two witnesses.

BERT H. HARRIS.
